If you listen very carefully, within the heavily accented English and banter, Maruyama-sensei has some profound words to say.
At the end of one class, he talked about the path of the learning process. He said that you could carry a student on your back down the path, but the student would become rather heavy to carry and s/he wouldn’t end up learning much. You could also guide the student, showing him where to go, which is less of a strain on your back, and soon the student learns to follow the way on his/her own.
In the end, Sensei said, the best thing we can do is to guide.
I have a strong back, but I can’t carry all that weight. Better to walk and point out things along the way.
